Abstract (en)
[origin: US6332911B1] In a method for the production of liquid metal, in particular liquid pig iron (9) or liquid steel pre-products, from metal carriers, in particular partially reduced or reduced sponge iron (3), in a melter gasifier (1) in which with supply of a carbon-containing material at least partially formed of fine coal (16) and coal dust (13) and with supply of oxygen or oxygen-containing gas the metal carriers are melted in a bed (4) of the carbon-containing material at the simultaneous formation of a reducing gas, optionally upon previous final reduction, fine coal (16) and coal dust (13) which are being charged, are mixed with bitumen (20) in the hot state, after undergoing a drying operation, and subsequently are cold-briquetted, and the briquettes (25) thus formed are charged to the melter gasifier (1) in the cold state and in the melter gasifier (1) are subjected to shock-heating.
